In flexible package, a one-way valve may include a substrate forming a portion of the flexible package and having at least one inlet score, a top sheet having at least one outlet score and secured thereto by an adhesive to define a valve chamber in which the substrate and the top sheet are not permanently adhered to each other, and a liquid film within the valve chamber and adhering the top sheet to the substrate within the valve chamber until a pressure differential exists causing gases to pass through the one-way valve. The inlet scores and the outlet scores may be non-linear, or may be linear scores that are not parallel to each other to prevent the scores from collapsing on themselves and preventing gas flow when the package buckles.

A waterproof dry bag with water potable material that utilizes a sealable connection to enable the user the option of collecting water and dispersing it through a bottom of the bag and which can be filtered with a water filter device. The bag can also be used to pump an air mattress.

An apparatus and method for supplying air to an interior of an athletic bag and/or to a piece of athletic equipment in the athletic bag (e.g., onto or into the piece of athletic equipment) is disclosed. The athletic bag includes a flow vent attached to a first wall of the bag and a hose attached (e.g., removably attachable) to the flow vent. The hose is configured to transfer air into an interior of the athletic bag and/or into or onto an interior of a piece of athletic equipment

A one-way valve integrated into a lamination of the kind used as a membrane seal for coffee containers and the like. The valve comprises a top layer, a substrate and a fluid polyol film. The top layer and the substrate are adhered together by an adhesive disposed between the top layer and the substrate. The adhesive defines a boundary of a valve chamber in which the top layer and the substrate are not permanently adhered to each other. The film enhances the adhesiveness of the top layer to the substrate in the area of the valve chamber so that gas inside the container does not escape until the internal pressure reaches a minimum value.

A steam release standing pouch has a structure in which the sealing portion is reliably peeled, and a content sealing standing pouch formed using the pouch. The steam release standing pouch has a first vapor passage portion. The distance between the inner edge of the tip of the vapor passage portion and the center of maximum expansion, which is the center of the portion where expansion is expected to be maximal, is shorter than either the distance between the inner edge of the first upper side portion and the center of maximum expansion or the distance between the inner edge of the first intermediate side portion and the center of maximum expansion.

The present invention relates to a package made from biodegradable polymeric flexible film for packaging fresh produce. The package includes at least a pair of opposite panels configured to form a receptacle. The package comprises plurality of apertures which are configured to provide a modified atmosphere packaging (MAP) for the fresh produce. The said film of package in conjunction with MAP facilitates humidity exchange through the polymeric structure of the film and controlled exchange of oxygen, carbon dioxide and other gases suitable for fresh produce, inside the package.
